f返回值是Awaitable, 就要用xxx_aync的函数
f返回值是Awaitable<bool>, 就要用if (await f)
self::functionA
return await EntAbc::queryFromReq($req)->queryMi->gen() |> vec ($$)
return await EntAbc::queryFromReq($req)->queryMi->gen() |> Vec\filter_nulls ($$)
Data Structure (Hack)
Vec: $a = vec[1, 2]
Dict: $b = dict["foot" => 2]
keyset: $c = keyset[1, 2]
const string USER_NAME = "we are";
static::USER_NAME
| Str\join | join成一个字符串 | $a = Str\join(Vec\reverse($vec), ','); |
| Str\format | 组成一个字符串 | $a = Str\format('%d is num', 2); |
| C\count | Vec的个数 | $a = C\count($requirements) |
| C\is_empty | Vec是否为空 | C\is_empty($requirement) |
| C\fb\any_async C\any | Vec中任意一个对应lambda返回true就return true | $has_deprecated_req = C\fb\any($requirements, async $requirement ==> {return true},); |
| Vec\map | Vec中每个对应lambda组成的新vec | $a = await Vec\map_async($requirements, async $requirement ==> {return await static::func(1)},); |
| Vec\filter | Vec中filter对应lambda组成的新vec | $a = Vec\filter($requirements, aysnc $requirement ==> 1 === 1,); |
| int->str | 类型转换 | $a = (string) $c |
| Vec\concat | 合并两个vec变成一个 | $c = Vec\concat($a, $b) |
| Vec\diff | 合并两个vec变成一个 | $c = Vec\diff($a, $b) |
| Vec\intersect | 求交集 | $c =Vec\intersect($a, $b) |
| C\count | Vec的个数 | $a = C\count($requirements) |
返回null或者属性 Shapes::ids($student, 'id')
shape('id' => 23)
->whereInstanceOf(Abc::class)
->where(P::asyncLambda(async $commit ==> await $commit ->...->genExistence),)
Ent
EntTag::genForceFromName($vc, 'pending')->getID()
Update
EntAction: EntCommitmentMutator::updateForObject($vc, $commitment,)->setLegal('abc')->genSaveX();
EntAction:
EntCommitmentMutator::updateForObject($vc, $commitment,)->actionUpdateStatus(Status::ABC)
->addTagIds(vec[$id])->genSaveX()
1. 自定义函数方法也就是contructor，否则需要每个都要setName('n')->setId(2)
2. 一连串动作
自动生成代码
1. Spec: EntFiled定义
2. Query: where语句
3. (controller): get方法,
4. TGraphQL~Fields: GraphQL fields, 需要再EntSchema config exposeAccessors
5. TEnt~Action: Trait内部文件，只要加入action就会产生，用于Ent~Mutator::updateForObject($vc, $ent)->addTags($data)->genSaveWithoutReload();
Create
EntCommitmentMutator::create($vc)->setName('abc')->genChangeset() // used for Ent triggers Ent
genSave, genSaveX //return null vs exception when save and load a updated Ent
EntQuery
get
gen
genOnlyValue <==> first()->gen()
queryAll: static function. Example: EntTag::queryAll($vc)
queryX: toEdge (Return edge object). Example: queryTag()->genOnlyValue()
queryFromX: fromEdge (Return self object)
得到一个Entity
1. $tag = EntTag::genForce($vc, $f-bid)
2. $tag = EntTag::qeuryAll($vc)->whereID(P::equals($f-bid))->gen()
nonnull
如果返回值为?EntTag, 用此法去掉问号$a as nonnull
GraphQL
<<GraphQLObject>>, <<GraphQLStrongObject>> 加到class中
<<GraphQLField>> 加到方法中
<<GraphQLRootField>> 加到getAllPets方法中定义GraphQL id为all_pets,
对应的GraphiQL:
{
all_pets {
id
}
}
<<GraphQLMutationRootField>>
在对应的Hack函数如GraphQL~MutationCall中定义，函数输入参数包括GraphQLInputObject
对应的GraphiQL:
mutation {
create_pet {
id,
ower
}
}
<<GraphQLEnum>>
<<GraphQLInputObject>> 自定义graphql类型如lat, lng
<<GraphQLInterface>>
<<GraphQLUnino>> generic返回类型
Relay
const data = usePreloadedQuery(
graphql`
query all_pets
`,
queryRef
);
queryRef = loadQuery(...)
const {node} = useLazyLoadQuery
如果只是读，不涉及写，一般只要加入到现成的GraphQL中即可。
data.post, node.sg in React
Fragment: 一部分query的alias，另其可复用
const data = useFragment(
const [addComment] = useMutation(
这是定义在叫Hook的JS文件中，包括写入到后端和onError，onComleted类似于Ajax的call
React
useState
export default function AbcComponent({
objectID,
showHeader = true,
}: Props): React.MixedElement {
const [counter, setCounter] = useState<number>(10); //10是初始值
return (
<div>{counter}</div>
<Another component
defaultProp = {counter}
/>
<Button
onPress={() => setCounter(counter - 1)}
/>
);
}
绑定后端数据到State
const [counter, setCounter] = useState(data[0].pet_name);
Flow
typed javascript: number, boolean, string, Map<string, Array<string>>
只用当变量用于component property时候采用花括号，如果在JS中不需要。
<Component
name={name}
/>
